That's a good stuff. I like this layout. I'm glad the necropolis came in handy too.

Regarding the size, one thing to consider with barrow set is a frame rate. I know I was already getting some fps drops when walking around this necropolis of mine, so it might happen too in a cell of this size as well, when you start detailing it with monsters, lights and stuff.

I know you asked to ignore it, but this dirty floor is actually quite cool, too.
